Tomo is a 2-in-1 educational programming robot kit, which can be assembled as either an intelligent tricycle or a smart
balance dicycle.The Tomo can be controlled through two apps, the “ODEV Explorer” and the “ODEV Blockly”. Both of which
can be found on the Apple App Store and Google Play. The ODEV Explorer app is for beginners and for more advanced
users please see the ODEV Blockly app. You can check the function of these apps on pages 22-23.

Introduction Parts List
Fun Facts
Screw thread callouts is a term used to
name specific types of screws. These
names are determined by “M”, the
“Number” x length of the screw (“M” is
the International Organization for
Standardization common screw threading
while “Number” refers to the diameter of
the screw).
For example Screw M4x16mm
•M is the ISO common screw threading
•4 is the diameter
•16mm is the length of the screw

Get moving with Tomo: After downloading the ODEV Explorer from Apple App Store or Google Play, open the app and
click “Controller”. The screen will prompt you to select the Dicycle or the Tricycle configuration. Choose the option based
on what you have built. Tap the Bluetooth connector button in the top right corner of the screen (gold circle) and place
your device directly above Tomo to connect.
(Please note: With the Dicycle configuration after successfully connecting you must toggle Tomo upright for the auto

2. Do not mix old and new batteries; do not mix the batteries with
different brands; do not mix the batteries with different types.
3. If the performance of the Tricycle or Dicycle is slow, it could mean
that the battery is low. Please replace the batteries.
4. If the robot is put in idle for a long time, please take out the batteries.
5. After each use, please turn off the power to prevent energy lost.
6. When installing the batteries, please make sure the positive and
negative sides of the batteries are installed correctly.

The gyro sensor integrated behind the main control plate can
detect the motion of the robot. After collecting the robot’ s motion
information, the gyroscopic sensor will use motion controller to
constantly adjust the motion of the robot to auto-balance the
robot. The gyroscopic sensor technology has been used on a
number of different applications such as RC products (Drones &
Helicopters), and mobile devices for changing screen orientation.
Ultrasonic SensorGyro Sensor
Ultrasonic sensor allows Tomo to avoid hitting objects through the use of its two probes that act as the receiver and the
emitter. The emitter first emits ultrasonic waves in all directions. As the emission begins, it triggers an internal timer to start
counting. When an ultrasonic wave hits an object and bounces back,the receiver will process it and the internal timer will stop.
The velocity of the ultrasonic wave in the air is 340m/s. Based on time that it took to hit the object and come back, the
distance between the object and the emitter can be calculated as .

APP: ODEV Explorer
ODEV Explorer app is used by beginners to control Tomo. It
includes four sections: Control, Task, Programming, and Cloud.
After installing ODEV explorer on your smart phone or tablet, you
can use your device to control the robot via Bluetooth on the
control network. Scan the below QR code to download the app.
(ODEV Explorer can be found from Google Play or Apple App Store)

Tracking Sensor APP
Tracking Sensor
The tracking sensor can identify the lines on the navigation
map that is included using the infrared emission and infrared
receiving tube, which has a high speed of detection.
You can also make your own tracking map with a black
marker or tape (the width of the line should be at least 1
inch).
Note: For more ways of using tracking sensor and more map
ideas, please visit our website at www.odevbot.com.

ODEV Blockly
APP: ODEV Blockly FAQ
ODEV Blockly is an intermediate-advanced app using graphical
programming as a tool to control Tomo. Children can create a small
program by dragging and stacking all kinds of programming
module blocks which will provide a directional path for Tomo. ODEV
Blockly can enable children to learn programming and explore the
full use of Tomo’ s directional and LED features. Please scan QR
code to download the ODEV Blockly app in Apple App Store and
Google Play.
Q: Why doesn't the robot respond after pressing the ON button?
1. Check to see if the batteries were installed correctly.
2. Press and hold the ON button for 3 seconds to turn on the robot (you should hear a beep
sound when the robot is on or off).
3. Make sure your phone or tablet has been connected to the robot via Bluetooth.
Q: Why does the robot move in the opposite direction from the control direction?
1. Exchange the motor wire connectors to resolve this issue.
Q: Why is the Dicycle unbalanced or unresponsive?
1. The power of battery may be low and needs to be replaced.
2. Make sure the motor wires are not touching the wheels. (you can use a tape to secure the
wires.)
3. The operating mode on the ODEV Explorer app that is selected is wrong. Please make
sure to choose Dicycle and connect it via bluetooth each time you open the app.
4. After successfully connecting Dicycle via Bluetooth, you must toggle Tomo upright for the
auto balance feature to begin.
Q: My smartphone/tablet is unable to connect to Tomo. What can I do?
1. Make sure the Bluetooth is enabled on your smartphone or tablet and keep it to a close
proximity to Tomo.
2. Try restarting the app, and restart Tomo.
Q: Why is the screw coming loose?
1. Due to the movement of Tomo, the screw may become loose during movement. It is
crucial to ensure that all the screws are fastened tightly.
Q: Why is the tracking sensor not working properly?
1. Do not use the tracking sensor under high exposure light.
2. The tracking sensor is installed above or below the recommended height.
3. Please check whether the wiring is connected correctly.
4. Please try to keep the tracking map flat.
